My ISP provides a single, dynamic IPv4 address to me. I have configured several tunnels, IPv4 in IPv4 and IPv6 in IPv4, to several sites. This is running on a very old Linux installation and I want to move that to a Debian system.
I know how to set up /etc/network/interfaces for such tunnels if the IPv4 address is static. However, with dynamic IPv4 address you do not only needed ifup <tunnel> and ifdown <tunnel> but also a way to update the remote tunnel configuration when the local IPv4 address changes. E.g. for Hurricane Electric tunnel broker you access a certain URL (using e.g. wget) where the URL encodes your current IPv4 address. At another site I need to execute a command using ssh. I know how I can do that using cron and/or pppd configs. But I'd like to know if Debian has some standard way to update tunnel configs, preferrably in /etc/network/interfaces with the rest of the interface definition. urs -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
